Two-piece obturator using “lock-and-key” mechanism
The Journal of Indian Prosthodontic Society, 2017 This paper describes a method used for the fabrication of a two-piece denture obturator for a patient who had surgical removal of the premaxilla due to squamous cell carcinoma. The patient had been wearing a two-piece obturator but encountered difficulty

The final step of 40S ribosomal subunit maturation is controlled by a dual key lock. [PDF]
Elife, 2021 Preventing premature interaction of preribosomes with the translation apparatus is essential to translation accuracy. Hence, the final maturation step releasing functional 40S ribosomal subunits, namely processing of the 18S ribosomal RNA 3’ end, is ...

Is the kernel-staples match a key-lock match? [PDF]
Chem Sci, 2018 We demonstrated the existence of homo-ligand–homo-kernel–hetero-staples phenomenon in metal nanoclusters and the remarkable change in their properties by subtle interfacial structure tailoring.

An Unusual Transorbital Penetrating Injury by House-key (lock): A Case Report with a Small Review of Literature. [PDF]
J Clin Diagn Res, 2015 Penetrating injuries of the brain are quite uncommon, comprising approximately 0.4% of all head injuries. In our case, a four-year-old boy who fell forward on a house-key (lock) accidentally while playing with some other children sustained a left sided ...

Dynamics of particles with “key-lock” interactions [PDF]
EPL (Europhysics Letters), 2008 The dynamics of particles interacting by key-lock binding of attached biomolecules are studied theoretically. Examples of such systems include DNA-functionalized colloids as well as nanoparticles grafted with antibodies to cell membrane proteins.

Acoustically levitated lock and key grains
Physical Review Research, 2023 We present a scheme for generating shape-dependent, specific bonds between millimeter scale particles, using acoustic levitation. We levitate particles in an ultrasonic standing wave, allowing for substrate-free assembly.

Complementary Lock‐and‐Key Ligand Binding of a Triplet Transmitter to a Nanocrystal Photosensitizer [PDF]
Angewandte Chemie, 2017 Owing to the difficulty in comprehensively characterizing nanocrystal (NC) surfaces, clear guidance for ligand design is lacking. In this work, a series of bidentate bis(pyridine) anthracene isomers (2,3-PyAn, 3,3-PyAn, 2,2-PyAn) that differ in their ...
